When Davos Seaworth arrives in White Harbor to try and persuade House Manderly to support Stannis Baratheon, the three Freys are already present. While Wendel was actually murdered by the Freys, Jared claims the Red Wedding was Robb Stark's doing and that Wendel died defending Lord Walder Frey from Robb Stark, who had changed into a rabid wolf. A shocked Davos calls Jared a liar. Jared draws his sword and is close to attacking Davos, but Wyman Manderly says he will have no bloodshed in Merman's Court.[5] Wyman is greatly angered, but pretends to agree with the Freys, as the Iron Throne holds hostage his surviving son and heir, Wylis Manderly. Wyman fakes Davos's death by having a criminal with similar features executed and his head dipped in tar so the Freys falsely believe him to be Davos. As a reward for proving his loyalty, Queen Cersei Lannister has Wylis Manderly returned to White Harbor.

According to Wyman Manderly, Rhaegar, Jared and Symond were given palfreys as "guest gifts" when the three Freys departed White Harbor.[7] Wyman claims they were all to meet at Winterfell for the wedding of "Arya Stark" to Ramsay Bolton. They have not been seen since, although Aenys Frey and Hosteen Frey, who were present at Winterfell, suspect Wyman Manderly of foul play.
